Mosquito Control

West Nile Virus

Adult mosquitoes are routinely collected and tested for West Nile Virus (WNV) in Hamilton County. When mosquitoes are found positive for West Nile Virus, truck mounted spraying will take place at sunset and cover a buffer area of approximately 1 mile around the positively sampled area. Truck mounted spray is not done for nuisance mosquitoes and is not harmful to humans or pets. West Nile Virus activity peaks in August and September so make sure you're protected.

Zika Virus

Zika virus is spread to people through mosquito bites. The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting from several days to a week. Severe disease requiring hospitalization is uncommon.

In May 2015, the Pan American Health Organization (PAHO) issued an alert regarding the first confirmed Zika virus infection in Brazil. The outbreak in Brazil led to reports of Guillain-Barré syndrome and pregnant women giving birth to babies with birth defects and poor pregnancy outcomes.

In response, CDC has issued travel notices for people traveling to regions and certain countries where Zika virus transmission is ongoing.

Mosquito Prevention Tips

Mosquitoes lay eggs in still water, which hatch in 7 to 10 days. If standing water is eliminated weekly, many mosquitoes will be kept from breeding in the first place...and with fewer mosquitoes, you can have more fun in your yard and throughout Indiana! Here are some things you can do:

Avoid mosquitoes by staying indoors at dawn and dusk when the bugs are most active.

Wear long-sleeved shirts and long pants while outdoors.

Apply insect repellent that contains DEET. Use only 10% DEET on children, and make sure everyone washes their hands well so that they do not get any creme in their eyes or mouth. Follow directions carefully.
